KIbI-hAGIsI can DUMP.

ll iyilicatiqn filed November declare the following to be a full, clear, and

exact description thereof.

My invg zntion relates to car dumping apparatus ot' the, type in which a loaded car is run upon a dump which is tilted to empty the car and from which the car is then re movedin the. opposite (lirection from that in whichflt comes upon the di'iuip. i The objcctot my invention is to provide rugizje I and effective device oi? the characterindicated which shall be provided with means for receiving-a car and stopping it withoutshoclv, and simmerout the use of shock-absorbinghorns such asare now coininbnly employed for this purpose, and which shall also have effective means for giving the empty car an impulse ()ifliitik in its reverse or outgoing direction. Morespeeifically, int object is to provide a car dump of the class indicated which, iii addition to the usual tracks forsupporting the car, shall have a. pair oi pivoted auxiliary tracksso arranged asto receive the car-and check itsaduancen1oven1ent,these inclined til'acks being provided with springs which assist in checking the movement oil the loaded car and also operateto raise the pivoted tracks and g ve the empty car ltS return impulse.

The accompanying (1 swing shows the manner in whichll new prefer to construct my innoroved car" dump, being understood, however, that various changes may be made yl ithout departing from my invention. Fig. 1 of the drawing isga side elevational view, with parts in section, of the complete appa ratus; Fig. 2 is a plairview of the con struction shown inl ig'. 1,31? 3 is a side elevational View similar to Fig. 1 showing the apparatus in dumping position; Fig. 4 is a lbngitudinal vertical sectionalview ot' the dump, the section being taken substantially e11 theline The: 2; Fig. is a front elevatiena l' View; andliig, 6 is a rear elevational new showing the braking mechanisin. a

In thedraiving,the numeral 2 indicates thesills, and the numeral 3 the flooring, oi

ailninping' platforni adjacent to whichis a 9, 1921'. Serial No. 514,010.

hopper i for receiving coal or other material from the dump. An opening in the flooringis provided between two the sills 2 and upon these sills are supported racks having teeth 6. The racks 5 act as supports for a tilting dump consisting of a floor plate 7 strengthened by transverse angle beams 8 and carrying parallel t-acks composedot angle beams 9 which are bolted in pairs uponthe floor plate 7, as shown in Fig. 5..

The dump is supported from the racks 5 by means of curved shoe-castings or rockers 1O having openings 11 corresponding; to the teeth 6 in the bar 5 and also having flanges 12 which are bolted to the opposite edges of the floor plate 7. The toothed engagement between therack teeth 6 andthe openings ll permits the dump structure to tilt without the use of a supporting shaft such as'is commonly employed in. tilting dumps. Safety guards 13 are preferably placed around. the rockers 10, as shown on Fig. i

Curved horns 14 are bolted between the torwanl ends of the track beams 9 for the purpose of limiting the torw ard movement of the cars which come upon the dump, These horns are not made yielding as is usually the case in dumps of this kind, but are rigid. with the floor plate and tracls,tl'ie shock of the cars being; absorbed by other means which will presentlybe described.

The rockers 10 have downward projections 15 which extend below thefl mr plate 7, as shown in F 1, and two channel bars 16 extend across and beneath the floor plate T modal-e attached at their ends by means oi bolts 17 to the projections It will be observed that the channel bars 16 are spaced somewhat below the floor plate 17, and that they are supported by the rockers amt pendently oi? the floor plate. Between each pairot angle bars 9, which,

as stated above, term the tracks on which side of the upper flanges of the channels 16. A spring 27 is compressed between the plate 24: and a smaller plate 28 below the plunger22.

It will be seen that these spring devices are both supported and guided by the channel plates 16 and that they tend to press the pivoted track members 20 into their upper or inclined position. The pressing of the springs 27 may be adjusted by means of the nuts on the bolts 25. The springs 27 are made strong enough to support the weight of an empty car but not strong enough to support the weight of a loaded car. Therefore, when the loaded car runs upon the dump the pivoted track members 20' are depressed by the weight of the car against the compression of the springs 27, and the forward movement of the car is thus checked. lVhen the car is emptied, the springs 27 can raise the track members 20 to their inclined position, which gives the emptycar a kick in the return direction. this kick resulting both from inclination of the track members and from the shape of the horns 14, the upper ends of which are curved backward. far enough to cause the "forward wheels of the cars to be squeezed past them and moved toward the rear as the pivoted track members are raised.

For the purpose of locking the pivoted flanges of the channel 16. Each oi the latch plates 30 is attached to one end of av rod 32 which extends through openings in the stiffening angles 8 and is pivoted at its rear end to a bell crank lever 33 that is pivoted at 34 between the track angles 9'and has a hammer 35 adapted to engage a plate 36 secured in the floor 3. A collar 37 is carried by each rod 32 and a spring 38 surrounds the rod between the co-llar37 and the angles 8.

The spring 38 forces the inner end of the latch plate 30 into a notch 39 in the plunger 22 whenever a loaded car comes upon the dump and depresses the track member 20 so as to bring the notch 39 into line with the latch 30.

As soon as. the dump begins to tilt and raises the hammer 35 ot the bell crank 33 of the plate 36, the spring 38 forces the latch 30 into the notch 39 where it remains until. the dump is rocked back to its starting position, at which time the hammer 35 ofthe'bell crank 33 strikes the plate 36 and rocks the bell crank on its pivot 34. thereby drawing the rod 32 to the left, Fig. 4, and so withdrawing the latch 32 lfrom the notch 39. The spring 27 is then free to raise the plunger 22 and tilt the track 20.

The floor plate 7 of the dump also carries two angle bars 40 which extend parallel to and midway between the tracks 9. These angle bars extend beyond the rear end of the floor plate 7 and serve to suspend a curved sword 41, the upper end of which is bolted between the ends of: the angles 40. A counterweight 42 is adjustably mounted on the angles 40 and assists in returning the dump to its level starting position after each car is dumped.

The sword 41. extends through an open ing 43 in the floor 3 and is engaged by z braking device, best shown on Figs. '1. and t). This braking device consists of :1V roller H which is loosely mounted in brackets elf) sccured beneath one of the beams 2. and a brake shoe 46 which engages the sword 41 opposite to the roller 4:47, and is pivoted at 47 to a plate 48 having a flange 49 that is secured beneath on of the beams 2 by means of bolts 50. An arm 51 is secured to the brake shoe 416 and carries an adjustable weight 52. An operating rope 53 has one end attached to the outer end of the arm 51. and extends up and over pulleys 54- to a handle 55 which is in convenient position to be grasped by the operator.

Ordinary rails 56 are shown in line with the tracks 9 to represent the tracks on which the loaded cars are brought to the dump. section ot' rail 57 extends across the hopper l and serves as a stop to limit. the tilting movement of the cars.

The dump starts its operation in the level position shown in Fig. 1 with the pivoted tracks 20 in their upwardly inclined position. A car C is run upon the dump from the left ot Fig. 1. and as it rides up on the inclined pivoted tracks 20 its forward momentum is checked. At the same time the tracks 20 yield under the weight of the loaded car, compressing the springs 27. The inclination of the pivoted tracks 20 and the strength of the springs 27 are so proportioned with respect to the normal speed at which the rars are delivered to the dump that the forward movement of the ca r has nearly ceased when the wheels of the car engage the ho ns 14. \Vben the car is in this position. as shown in tull lines on Fig. l. the operator grasps the handle 55 and pulls on the rop which releases the brake shoe 56 from the sword 41 and permits the dump and the car to rock forward on the rockers 10. the weight oi the dump being so distributed that the center of gravity is at this time on the right of the rocker 10. as seen in Fig. 1. The dump and the car then rock to the position shown-in Fig. 3, the operator car, which is of the open-end type,dis-

manipulating the brake so as to avoid shock as far as possible, and the movement oi the car beinglimited by the stop rail The charges itsloa d into thehopper l, andthe dump immediately returns from the tilted position of Fig. 3 to the horizontalposition counter-weight 4-2. i i

soon as the car begins to IOClK to the dumping position, the latches 30 enter the notches 39 in the plunger 22 inthe manner described"above, and holdthe plungers in their downward orretracted position; When of Fig. 1, being assistedin so doing by ihe the dump; returns to itshorizontal position the bell cranks :33 withdrawpthelatches 3O iroin the notchesilgi and the springs 27 which, as stated, are strong; enoughto raise the emptycar, immediately lift the pivoted tracks to their inclined position. This at once causes thecar to be moved to the fear, because the iorwardwheels ofthe car are beneath the'overhanging ends of the iii sem n and the upward movement of the tracks 20 causes the, horns to exert a wedge int; ei lect onqtheqvheels which gives the car a backward kick. Vi hen the rails 20 rise to [their inclined position the car is on a down-hill track and at once rolls from the dump which. is then to receiveanother loaded car, and the operation is repeated described. above.

The details of construction which I have shown and descrlbedproduce a rugged and.

satisfactory car dump, but such details may i of course be varied inmany respects, and

I tl' ere'loi'e wish it to beunderstood that my i invention is not restricted to this specific coustruction but is limited only by the scope of the appended claims.
